"Pitch Ratio" Pitch Processor Module

Another Pitch Processor module that would make sense is a frequency ratio multiplier module.
For example, it could multiply the incoming signal by 2/3 (perfect fifth) this would be useful for FM and Ring modulation.
I'm thinking of adding to dials one for the numerator and one for the denominator, both with [1, 16] range. This would give enough range to achieve a minor second ratio, which is 16/15.

Released as part of the Mela 4.1 update.

Sounds like this will be very useful. Is it possible to also apply harmonic ratios like this to multiple instances of bandpass filters? I've played a little with pitched-noise patches, and I know how to route main keytrack to frequency for a single filrter instance, setting base freq to 262 to match pitch correctly for the fundamental... but would a module like this make it easier to add additional harmonics? I guess if I just calculate the ratios and offset base freq in each filter manually, it would give the same result.

Jon Diercks: The good thing about Key Tracking modulator and Filter Cutoff frequency ranges span exactly 10 octaves. And looks like you've utilised this yourself. And, yes for now doing something like that means manually mapping to multiple filters and their cutoff frequencies. I think what we would need is a module that can modify a modulator signal. Like multiplier or something. And I'm planning to add modulator signal modifiers. But a Pitch Ratio module only modifies a Pitch signal. We could consider a possibility where we could have a Modulator module which takes a Pitch signal and generates a modulator signal, but don't know how useful it would be. It seems Key Track could do the job. Anyway, I'll have to think about various possibilities more to see if there's anything useful that can be done for your case.

Nikolozi: thanks for clarifying. I think it could be really interesting to have modules that allow for conversions between all signal types.

The initial implementation is now available in build 78. I'm considering adding a visual display of the ratio, maybe even reducing the to coprimes. e.g. So instead of showing 4/6, it will show 2/3 ratio.
